Scientists have found that young stellar cousins of our Sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a new study using NASA’s Chandra X-ray Observatory. A paper describing the results published Monday in The Astrophysical Journal. Unlike in the new movie “Project Hail Mary,” this quieting […]

Hubble Spies an Active Spiral
A luminous swirl set against the deep black of space, the barred spiral galaxy IC 486 glows with a soft, ethereal light in this new NASA Hubble Space Telescope image. IC 486 lies right on the edge of the constellation Gemini (the Twins), around 380 million light-years from Earth. Classified as a barred spiral galaxy, […]
NASA Webb, Hubble Share Most Comprehensive View of Saturn to Date
NASA’s James Webb Space Telescope and Hubble Space Telescope have teamed up to capture new views of Saturn, revealing the planet in strikingly different ways. Observing in complementary wavelengths of light, the two space observatories provide scientists with a richer, more layered understanding of the gas giant’s atmosphere. Both sense sunlight reflected from Saturn’s banded […]
NASA’s Hubble Revisits Crab Nebula to Track 25 Years of Expansion
A quarter-century after its first observations of the full Crab Nebula, NASA’s Hubble Space Telescope has taken a fresh look at the supernova remnant. The result is an unparalleled, detailed look at the aftermath of a supernova and how it has evolved over Hubble’s long lifetime. A paper detailing the new Hubble observation is published […]

NASA’s Hubble Unexpectedly Catches Comet Breaking Up
In a happy twist of fate, NASA’s Hubble Space Telescope just witnessed a comet in the act of breaking apart. The chance of that happening while Hubble watched is extraordinarily minuscule. The findings published Wednesday in the journal Icarus. The comet K1, whose full name is C/2025 K1 (ATLAS)—not to be confused with interstellar comet […]
NASA Discovers Crash of Extreme Stars in Unexpected Site
A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an environment like this before — and it may help solve two outstanding cosmic mysteries. A paper describing these results […]
Listen to This Month’s ‘Planetary Parade’ With NASA’s Chandra
In late February, people in the Northern Hemisphere can look up for a special sight : Six planets will all be visible from clear and dark night skies. New sonifications from NASA’s Chandra X-ray Observatory released [day of week] will help commemorate this latest “planetary parade.” Because the planets in our solar system travel around […]
